CROSS REFERENCE TO RELATED APPLICATIONS

This application is a Continuation of U.S. patent application Ser. No. 16/637,029, filed on Feb. 6, 2020 which is a Continuation of PCT International Application No. PCT/KR2018/009020, which was filed on Aug. 8, 2018, which claims priority to Korean Patent Application No. 10-2017-0101434, which was filed on Aug. 10, 2017, the contents of which are incorporated herein by reference.

TECHNICAL FIELD

The disclosure relates to technologies of processing radio frequency (RF) signals of different frequency bands.

BACKGROUND ART

With the development of information technology (IT), various types of electronic devices such as smartphones and tablet personal computers (PCs) have come into wide use. The electronic devices may wirelessly communicate with another electronic device or a base station using their antennas. According to 4G wireless communication standards, a mobile network operator may provide a wireless communication service to a user of the electronic device by using frequency bands authorized by a country (authority) among various frequency bands.

The frequency bands may be divided on the basis of, for example, a frequency range defined by 3^(rd) generation partnership project (3GPP). One frequency band may have a bandwidth of dozens and hundreds of MHz. The frequency bands may be roughly classified into a low band, a mid band, and a high band according to relative frequency height.

The electronic device may transmit signals with the above-mentioned frequency bands to a base station (or another electronic device) or may receive signals with the above-mentioned frequency bands from the base station (or the other electronic device). The electronic device may include, for example, an RF block optimized for the low band, the mid band, or the high band.

To enhance quality or a download speed of a signal received by the electronic device, technologies such as carrier aggregation (CA) or Rx diversity have been developed. Respective countries and/or operators provide an enhanced communication service to the user through so-called CA of aggregating two or more frequency bands.

DISCLOSURE Technical Problem

CA may be performed between lower frequency bands, included in a low band, a mid band, and a high band. For example, any one frequency band which belongs to the mid band and any one frequency band which belongs to the high band may be aggregated into each other. Meanwhile, because a frequency band adopted for implementing the CA is able to differ for each network operator, an electronic device should be able to implement CA using combinations of various frequency bands as many as possible. To implement CA using the various combinations, additional antennas and related components may be required. However, because a mounting region of a smartphone or a tablet PC is limited, it is very difficult for the electronic device to implement CA using combinations of various frequency bands.

According to embodiments of the disclosure, an aspect of the disclosure is to provide a method for implementing CA using combinations of various frequency bands by efficiently using an RF block and an antenna and an electronic device for performing the same.

Technical Solution

In accordance with an aspect of the disclosure, an electronic device is provided. The electronic device may include a first antenna, a second antenna, a filter, electrically connected with the first antenna, including a first connecting terminal corresponding to a first frequency band and a second frequency band capable of being transmitted or received via the first antenna, and a second connecting terminal corresponding to a third frequency band capable of being transmitted or received via the first antenna, a first wireless module including a first transmit and receive circuitry for processing a signal of the first frequency band and a signal of the second frequency band, a second transmit and receive circuitry for processing a signal of the first frequency band and a signal of the second frequency band, a first transmission and reception connection terminal connected with the first connecting terminal, and a second transmission and reception connection terminal connected with the second antenna, and a first switch for connecting the first transmit and receive circuitry and the second transmit and receive circuitry with the first transmission and reception connection terminal or the second transmission and reception connection terminal, and a second wireless module including a third transmit and receive circuitry, electrically connected with the second connecting terminal, for processing a signal of the third frequency band.

In accordance with another aspect of the disclosure, an electronic device is provided. The electronic device may include a first antenna element configured to transmit and receive a signal of a first frequency band or a second frequency band, a second antenna element configured to transmit and receive a signal of the first frequency band or the second frequency band, a first RF block, electrically connected with the first antenna element and the second antenna element, including a first transmit and receive circuitry and a second transmit and receive circuitry, an RF receive circuitry for receiving the signal of the first frequency band or the second frequency band from the first antenna element or the second antenna element, and a transceiver connected with the first RF block and the RF receive circuitry. The first transmit and receive circuitry may process the signal of the first frequency band or the second frequency band. The second transmit and receive circuitry may process the signal of the first frequency band or the second frequency band. The transceiver may perform carrier aggregation (CA) for the signal of the first frequency band and/or the signal of the second frequency band using the first transmit and receive circuitry and the second transmit and receive circuitry and may perform diversity for signals received from the first RF block and the RF receive circuitry.

In accordance with another aspect of the disclosure, a method is provided. The method may include transmitting and receiving a signal of a first frequency band or a second frequency band via an antenna element, performing CA for the signal of the first frequency band and/or the second frequency band using a first transmit and receive circuitry and a second transmit and receive circuitry, which are included in a first RF block, and performing diversity for the signal of the first frequency band or the second frequency band using the first RF block and an RF receive circuitry.

Advantageous Effects

In the disclosure, a frequency band may refer to a band defined in 3GPP. The frequency band and the band may be interchangeably referred to as each other in the disclosure. The bandwidth may refer to an uplink or downlink frequency range of a frequency band. The uplink frequency range and the downlink frequency range are distinguished from each other in a frequency division duplex (FDD) mode, whereas the uplink frequency range and the downlink frequency range are the same as each other in a time division duplex (TDD) mode. Furthermore, each frequency band may be divided into a low band, a mid band, and a high band according to a used bandwidth. For example, according to the 3GPP band definition, each band may be divided into three groups, such as low/mid/high bands, like Table 1 below according to an assigned bandwidth.

Each band may be categorized into a first frequency band, a bandwidth of which belongs to a first frequency range, a second frequency band, a bandwidth of which belongs to a second frequency range, and a third frequency band, a bandwidth of which belongs to a third frequency band. Herein, the second frequency range may be defined to be greater than a maximum value of the third frequency range and is less than a minimum value of the first frequency range. In an embodiment, the first frequency band, the second frequency band, and the third frequency band may correspond to the high band, the mid band, and the low band, which are defined in 3GPP, respectively.

According to various embodiments, the first frequency band, the second frequency band, and the third frequency band may be defined to be different from those in the 3GPP. For example, a band using a frequency of 2000 MHz or more may be defined as the first frequency band.

In an embodiment disclosed in the disclosure, the first frequency band will be described as being a high frequency band, the second frequency band will be described as being an intermediate frequency band, and the third frequency band will be described as being a low frequency band. For example, the low frequency band may be about 700 MHz to 900 MHz, the intermediate frequency band may be 1.4 GHz to 2.2 GHz, and the high frequency band may be about 2.3 GHz to 2.7 GHz. However, categorization criteria may be defined different from being provided in the above example or 3GPP standards and may be categorized into 4 or more frequency bands.

According to an embodiment, the power source may include a supply modulator. The supply modulator may adjust the voltage (or current) of supply power depending on intensity of a signal input to the PA included in the first transmit and receive circuitry 231. For example, the supply modulator may adjust a voltage waveform of supply power to follow an envelope of a PA input signal (so-called envelope tracking). Power efficiency may be enhanced by the supply power adjustment of the supply modulator.

The processor 280 (e.g., a processor 120 of FIG. 1 ) according to various embodiments may be electrically connected with, for example, the components included in the electronic device 201 and may execute calculation and/or data processing about control and/or communication of the components included in the electronic device 201.

The first RF block 301 according to various embodiments may include a first transmit and receive circuitry 311, a second transmit and receive circuitry (321), a first switch 331, and a second switch 341. In various embodiments, the first RF block 301 may exclude at least one of the components or may additionally include another component. For example, the first switch 331 or the second switch 341 may be omitted or may be located outside the first RF block 301. According to various embodiments, as the RF receive circuitry 302 is located in the first RF block 301, it may become an additional component of the first RF block 301. For another example, a first transmission and reception connection terminal 351 and a second transmission and reception connection terminal 361 may be included in the first RF block 301. In various embodiments, the first transmission and reception connection terminal 351 may be connected with the first antenna element 303, and the second transmission and reception connection terminal 361 may be connected with the second antenna element 304.

The first transmit and receive circuitry 311 according to various embodiments may include a first multiplexer 311_1 and a second multiplexer 311_2. In various embodiments, the first transmit and receive circuitry 311 may additionally include another component other than the components. For example, the first transmit and receive circuitry 311 may further include at least one PA or at least one LNA.

Each of the first multiplexer 311_1 and the second multiplexer 311_2 according to various embodiments may select any one of two PA output terminals and two LNA input terminals and may connect the selected terminal with the first switch 331. For example, the first multiplexer 311_1 may select any one of an output terminal 31 of a first PA 311_1 a for transmitting a first signal of a first frequency band, an output terminal 32 of a second PA 311_1 b for transmitting a second signal of the first frequency band, an input terminal 33 of a first LNA 311_1 c for receiving the first signal of the first frequency band, and an input terminal 34 of a second LNA 311_1 d for receiving the second signal of the first frequency band and may connect the selected terminal with the first switch 331.

According to an embodiment, the PAs (e.g., 311_1 a and 311_1 b) included in the first transmit and receive circuitry 311 and the second transmit and receive circuitry 321 may be connected with the transceiver 305 via a switch 311_S1. The PA selected by the switch 311_S1 may be connected with the transceiver 305, and a signal received from the transceiver 305 may be transmitted to an external device (e.g., a base station or another electronic device) via the PA.

According to an embodiment, the LNAs (e.g., 311_1 c and 311_1 d) included in the first transmit and receive circuitry 311 and the second transmit and receive circuitry 321 may be connected with the transceiver 305 via a switch 311_S2. The LNA selected by the switch 311_S2 may be connected with the transceiver 305, and a signal received from the external device may be transmitted to the transceiver 305 via the selected LNA.

In an embodiment, the number of PAs or LNAs connected with the first multiplexer 311_1 or the second multiplexer 311_2 may be combined in various manners. For example, the first multiplexer 311_1 may be connected with three PA output terminals and one LAN input terminal.

In an embodiment, control of the first multiplexer 311_1 and the second multiplexer 311_2 may be performed by the processor 306. For example, when wanting to transmit an RF signal, the processor 306 may control the multiplexers 311_1 and 311_2 to connect an output terminal (e.g., 31 or 32) of the PA with the first switch 331. When wanting to receive an RF signal, the processor 306 may control the multiplexers 311_1 and 311_2 to connect an input terminal (e.g., 33 or 34) of the LNA with the first switch 331. In an embodiment, the processor 306 may control the multiplexers 311_1 and 311_2 to transmit or receive a signal of a specific band. For example, the processor 306 may control the first multiplexer 311_1 such that the output terminal 31 of the first PA 311_1 a is connected to the first switch 331 to transmit a signal transmitted from the first PA 311_1 a.

In an embodiment, the first multiplexer 311_1 and the second multiplexer 311_2 may be designed to process signals of different frequency bands. For example, the first multiplexer 311_1 may engage in transmitting or receiving a signal of the first frequency band, and the second multiplexer 311_2 may engage in transmitting or receiving a signal of the second frequency band.

The second transmit and receive circuitry 321 according to various embodiments may have the same or similar configuration to the first transmit and receive circuitry 311. The second transmit and receive circuitry 321 may include a third multiplexer 321_1 and a fourth multiplexer 321_2. The third multiplexer 321_1 and the fourth multiplexer 321_2 may correspond to the first multiplexer 311_1 and the second multiplexer 311_2, respectively.

The first switch 331 according to various embodiments may connect the first transmit and receive circuitry 311, the second transmit and receive circuitry 321, or the RF receive circuitry 302 with the first antenna element 303 or the second antenna element 304. The first switch 331 according to another embodiment may connect the first transmit and receive circuitry 311, the second transmit and receive circuitry 321, or the RF receive circuitry 302 with the first transmission and reception connection terminal 351 or the second transmission and reception connection terminal 361. The first transmission and reception connection terminal 351 may be connected with the first antenna element 303, and the second transmission and reception connection terminal 361 may be connected with the second antenna element 304.

According to an embodiment, the first switch 331 may include a plurality of single pole single throw (SPST) switches. In an embodiment, the first multiplexer 311_1 and the second multiplexer 311_2 of the first transmit and receive circuitry 311, the third multiplexer 321_1 and the fourth multiplexer 321_2 of the second transmit and receive circuitry 321, and the RF receive circuitry 302 may be connected with a pole of the first switch 331. The pole may refer to an arm capable of moving the switch, and a throw may refer to the number of paths with which one pole may come into contact. For example, the SPST switch may have one movable arm, and the arm may come into contact with or come off one path. According to an embodiment, each of the multiplexers 311_1, 311_2, 321_1, and 321_2 and the RF receive circuitry 302 may be connected with the first antenna element 303 or the second antenna element 304 by two SPST switches which are movable independently.

According to an embodiment, the first switch 331 may be controlled by the processor 306. In an embodiment, the processor 306 may control the first switch 331 such that any one of the first multiplexer 311_1 and the second multiplexer 311_2 is connected with the first antenna element 303 and such that any one of the third multiplexer 321_1 and the fourth multiplexer 321_2 is connected with the second antenna element 304 to perform CA. For example, the processor 306 may control the first switch 331 such that the first multiplexer 311_1 is connected with the first antenna element 303 and such that the third multiplexer 321_1 is connected with the second antenna element 304. In this case, the processor 306 may perform uplink CA or downlink CA using one of two bands selectable by the first multiplexer 311_1 and one of two bands selectable by the third multiplexer 321_1.

According to an embodiment, the processor 306 may control the first switch 331 such that any one of the first multiplexer 311_1, the second multiplexer 311_2, the third multiplexer 321_1, or the fourth multiplexer 321_2 is connected with the first antenna element 303 and such that the RF receive circuitry 302 is connected with the second antenna element 304 to perform diversity. For example, the processor 306 may control the first switch 331 such that the first multiplexer 311_1 is connected with the first antenna element 303 and such that the RF receive circuitry 302 is connected with the second antenna element 304. In this case, the same signal which belongs to the same band may be received via the first RF block 301 and the RF receive circuitry 302, and the processor 306 may perform diversity using the received signal.

According to an embodiment, when performing the CA or diversity and when a specific multiplexer for a selected band and an antenna are connected with each other, the processor 306 may allow the other multiplexers not to be connected with the antenna elements 303 and 304. When the processor 306 will perform CA between signals of the first frequency band, because there is a need to block a signal of the second frequency band, the processor 306 may allow the second multiplexer 311_2 and the fourth multiplexer 321_2 not to be connected with the antenna elements 303 and 304.

Through the process, an electronic device (e.g., an electronic device 201 of FIG. 2 ) may perform CA using various combinations between four bands of the first frequency band and four bands of the second frequency band and may perform diversity for each band.

The second switch 341 according to various embodiments may connect between the RF receive circuitry 302 and the first switch 331. In an embodiment, the second switch 341 may be omitted. In other words, the RF receive circuitry 302 and the first switch 331 may be directly connected with each other. The RF receive circuitry 302 may include a fifth multiplexer 312 and a sixth multiplexer 322, and the second switch 341 may select any one of the fifth multiplexer 312 and the sixth multiplexer 322 and may connect the selected multiplexer with the first switch 331. In an embodiment, the second switch 341 may be controlled by the processor 306 based on the signal received by the RF receive circuitry 302.

According to an embodiment, LNAs included in the RF receive circuitry 302 may be connected with the transceiver 305 via a switch 312_S1. The LNA selected by the switch 312_S1 may be connected with the transceiver 305, and a signal received from the external device may be transmitted to the transceiver 305 via the selected LNA.
